Description
There is evidence for a 130 GeV $\gamma$-ray line at the Galactic Center in the \emph{Fermi} Large Area Telescope data. Dark matter candidates that explain this feature should also annihilate to Standard Model particles, resulting in a continuous spectrum of photons. To study this continuum, we analyze the \emph{Fermi} data down to 5 GeV, restricted to the inner $3^\circ$ of the Galaxy. We place a strong bound on the ratio of continuum photons to monochromatic line photons that is independent of uncertainties in the dark matter density profile. Neutralino dark matter is excluded by the derived constraints.
